Innovative solutions for quantum error correction are needed to implement quantum computing, which requires the use of hundreds of logical qubits in a fault-tolerant manner. Researchers from our group, in collaboration with the theory team of Professor Markus Müller at RWTH Aachen University and Forschungszentrum Jülich, have now demonstrated a technique that makes it possible to perform a quantum operation between superconducting logical qubits while correcting for potential errors occurring during the operation. The results were just published in Nature Physics. This demonstration of lattice surgery on superconducting qubits marks an important step towards the ambitious goal of building useful quantum computers.
